Application of probiotics in commercial layer diets: a review

Abstract

Probiotics of various commercial preparations are being considered worldwide for poultry as performance enhancers and suitable alternatives to antibiotics. Much of the previous efforts to explore beneficial effects of probiotics were directed for commercial broilers and scientific information for commercial layer nutrition is limited in contrast to that of broilers. To our knowledge, whatever information is available, no attempt has been made as yet to make a comprehensive review of the effects of probiotics on layer chicken covering different aspects of production. This review is prepared by consolidating and updating information available in the literature covering laying performance, serum chemistry, egg quality and its safety aspects. Data generated from a number of studies clearly indicated that apart from a few exceptions, probiotics are found to be effective for the improvement of laying performance; serum biochemical parameters, egg shell and albumen quality and they are suitable for the production of safe eggs. Effect of probiotics on layers is mediated by boosting up gut health thereby creating an environment for better nutrient assimilation and thus an improvement of production and egg quality is achieved. Factors affecting such results need to be assessed more precisely since they contribute to some contradictions in the literatures. Nevertheless, the feed industry can rely on probiotics as quite safe for the production of quality feed to support commercial layer nutrition.

Laying hen responses to multi-strain Bacillus-based probiotic supplementation from 25 to 37 weeks of age

“…Considering probiotic supplementation for layers, several bacterial strains including Lactobacillus, Enterococcus, and Saccharomyces cerevisiae have been reported to result in the modulation of intestinal microbial populations, higher laying performance, and improved egg quality [7,8,9]. Suggesting probiotic involvement in mineral absorption and bone mineralization, increased tibia density, ash, and P contents have been reported with the supplemental Bacillus species [10,11].…”

Detoxification Impacts of Dietary Probiotic and Prebiotic Supplements Against Aflatoxins: An Updated Knowledge – A Review

“…Probiotics may thus be effective tools for reducing the harm that aflatoxin in the chicken business does to the economy and public health. Likewise, Chowdhury et al (2020)"revealed that dietary probiotics might increase laying performances and egg quality in terms of shell and albumen quality. Utilizing probiotics helps to enhance the biochemical blood markers of total cholesterol, triglycerides, LDL cholesterol, and HDL cholesterol.…”

Benefits of Probiotics on Aflatoxin Infected Birds

“…Application of biotechnological tools to reduced chemical residues and improved production efficiency that does not create any harm to poultry as well as consumers of the value chain [83]. Recent advancement in biotechnology on poultry feeds, banning of harmful growth promoters and antibiotics.…”

“…Recent advancement in biotechnology on poultry feeds, banning of harmful growth promoters and antibiotics. Globally, probiotics is gaining acceptance in feed formulation [83]. Antimicrobial resistance is now a worldwide threat [84] with alteration of immune response due to feeding of antibiotic growth promoters, Probiotics are considered as an important tool as regard to antimicrobial resistance [85].…”
